Hookup- he was acting different

So I just hooked up w this guy today and we’ve hooked up in the past and were already planning it this weekend. So we did and I told him a week ago that I don’t want to get too close to him bc tbh I don’t really click w him it’s just good sex. And he said he understood and I don’t think he’d ever have feelings for me, we just are really different. So today we were having sex and I couldn’t tell if he was just trying not to cum too quick or what. He seemed like quieter and not as kinky as I thought he was. However the past times we were really drunk when we had sex. Idk and he was making convo and he seemed like he was trying to be a gentleman and I thought he was an ass this whole time lol. But he came twice so I think he might’ve just been focusing on not coming too quick idk?
